Pretty good account of the Dalton Gang's ill fated attempt to rob two banks at once in Coffeyville. Has both old and new pix. Start with post #89. When you get through, go back to the start for some good history of southern Kansas.
I spend way too much time on Adventure Rider. It is definately motorcycle porn. In a clean way.
